5-Aminotetrazole is an organic compound with the formula HN 4 CNH 2. It is a white solid that can be obtained both in anhydrous and hydrated forms. The molecule is planar. [1] The hydrogen bonding pattern in the hydrate supports the assignment of NH being adjacent to carbon in the ring. [2]
Other tetrazoles are used for their explosive or combustive properties, such as tetrazole itself and 5-aminotetrazole, which are sometimes used as a component of gas generators in automobile airbags. Tetrazole based energetic materials produce high-temperature, non-toxic reaction products such as water and nitrogen gas, [ 19 ] and have a high ...
As a general rule, PETN is considered to be either a relatively insensitive primary explosive, or one of the most sensitive secondary explosives. PETN may be detonated by striking with a hammer on a hard steel surface (a very dangerous thing to do), and is generally considered the least sensitive explosive with which this may be done.
It has been more than 30 years since we conducted an underground nuclear explosive test.” The Los Alamos National Lab in northern New Mexico and Lawrence Livermore National Lab in California ...
Determination of the shock sensitivity of a material intended for practical use is one important aspect of safety testing of explosives. A variety of tests and indices are in use, of which one of the more common is the Rotter Impact Test with results expressed as FoI (Figure of Insensitivity.) At least four other impact tests are in common use ...
It is a key, directly measurable indicator of explosive performance, but depends on density which must always be specified, and may be too low if the test charge diameter is not large enough. Especially for little studied explosives there may be divergent published values due to charge diameter issues.
The test continues with each sample tested at a stimulus 1 step up or down from the previous stimulus if the previous result was negative or positive. The results are tabulated and analyzed via Bruceton analysis, a simple computation of sums that can be performed by pencil and paper, to provide estimates of the mean and standard deviation.
